---

1. Shell Script: Reverse a Number

• Task A: Write a shell script to reverse a given number.
• Task B: Implement the FCFS scheduling algorithm in C (assume all processes arrive at time zero).

---

2. Shell Script: Factorial Calculation

• Task A: Write a shell script to calculate the factorial of a given number.
• Task B: Implement the SJF scheduling algorithm in C (assume all processes arrive at time zero).

---

3. Shell Script: Prime Number Check

• Task A: Write a shell script to determine if a number is prime.
• Task B: Implement the Priority scheduling algorithm in C (assume all processes arrive at time zero).

---

4. Shell Script: Odd or Even Check

• Task A: Write a shell script to check if a number is odd or even.
• Task B: Implement the Round Robin scheduling algorithm in C (assume all processes arrive at time zero).

---

5. Shell Script: Leap Year Check

• Task A: Write a shell script to determine if a year is a leap year.
• Task B: Create a process using fork() and replace the child process image with ls.

---

6. C Program: Parent-Child Communication

• Task A: Write a C program to pass a message from the parent to the child process using pipes.
• Task B: Write a C program to implement the ls | sort operation.

---

7. C Program: Thread Creation and IDs

• Task A: Write a C program to create a thread from the main thread and print the thread ID and process ID of both.
• Task B: Write a shell script to find the maximum of three numbers using if-else.

---

8. C Program: Thread Character Count

• Write a C program to create a thread that counts the number of characters input by the main thread. Use semaphores to manage simultaneous execution.

---

9. C Program: Producer-Consumer Problem

• Write a C program to implement the Producer-Consumer problem using semaphores.

---

10. C Program: Reader-Writer Problem

• Write a C program to implement the Reader-Writer problem using semaphores.

---

11. Threaded Operations and Shell Script

• Task A: Write a C program to create two threads:
  • Thread 1 calculates the factorial of a number.
  • Thread 2 reverses a number.
    Both threads return their results to the main thread.
• Task B: Write a shell script to swap two numbers without using a third variable.

---

12. C Program: Banker's Algorithm

• Write a C program to implement the Banker's Algorithm for deadlock avoidance.
